Water pollution is the contamination of water bodies from both direct and indirect discharge of pollutants without proper treatment, which affects plants and organisms living in these bodies of water and damages natural biological communities. Pollutants discharged into lakes, rivers, oceans, aquifers and groundwater can contaminate water supplies and harm individual species and populations.

3.  Water pollution is the contamination of water
bodies (e.g. lakes, rivers, oceans, aquifers and
groundwater). Water pollution occurs when
pollutants are directly or indirectly discharged
into water bodies without adequate treatment
to remove harmful compounds.
 Water pollution affects plants and organisms
living in these bodies of water. In almost all
cases the effect is damaging not only to
individual species and populations, but also to
the natural biological communities.
